This is a really interesting combination of genres; I never expected to see a shooter and a farming sim merged together! I only played through a handful of waves, but I had fun doing so.
The art style is amazing, lots of charm!
On the sound design front, the sound for picking up the coins is satisfying. I would have liked for some more-intense music during combat.
In liked that there was a satisfying amount of money; it felt like there was always something to buy. But I felt like when harvesting, the coins launched too far, such that walking around to pick them all up was kind of a chore.
Spinning unfortunately ends up not being the winning strategy here because of the need for aim, such that clicking and wiggling back and forth in a tiny arc is the reliable way to hit things. I think the game would be much more fun without the spin mechanic. Once I got the hang of aiming, combat was a breeze; definitely out of scope for a week-long jam, but some more enemy variety would be nice as well.
I think there's something really cool with this mix of genres; for me, though, I would have liked to see them interact with each other in some way (maybe enemies come and eat your crops if you haven't harvested them, or maybe there are other ways). Right now it felt like two separate games stuck together, and I feel like it would be really awesome for them to play off of each other more.
All-in-all, this was a cool game and I had fun with it. I'm really intrigued by the genre mix, and the art is so cute! Great work.
